Description

This class is used to dump nodes and their children in an XML format.

The xml method can be called on individual elements in the tree to dump these as fragments:

say '<Document>';
say .xml(:depth(2)) for $tags.find('Document//Sect');
say '</Document>';

Calling $node.xml(|c), is equivalent to: PDF::Tags::XML-Writer.new(|c).Str($node)
